Graphics cards keep failing

[joey59]

So i've gone through 2x asus strix 1060 cards over the last year, each time was a bit different but prevented the gpu from working, like it stopped putting out a display, wixilate the screen, pc freezes, only gpu fans go to 100% gpu LED lights shut off, etc....

Mobo is a MSI b350, called msi to see if theh could test it and on the phone and rma email i was told it way take up to 50 business to get the mobo back, what could most likely cause this, Mobo, PSU or somthing else?
PSU is a EVGA 650g nex gold.

Asus said its possible for the pcie slot to build static but didnt talk much about it.

First gpu lasted maybe 7-8 months, second lasted anothed about the same time.

Replacement gpu should arrive soon, should i just use it, send in the mobo and risk it taking soo long to get it back or look at psu?

Are you using any sort of surge protector for your PC?

I would definitely invest in one, it's important to provide "clean" power to your computer.

Personally, I wouldn't wait 50 business days. It's just really hard to say what your issue could really be.

More than likely just a pair of duff graphics cards. Static building up on the pcie slot? Load of rubbish. Static doesn't build up on connectors like that.

I agree, likely you had a dud card. Do you know if they sent you a new card or a refurbished card as a replacement?

Particularly on these newer boards with the metal slot reinforcement would take any static charge to ground.

Possibly a bad power supply or the motherboard itself. Really the only way to look for an electrical fault would be with an oscilloscope and carefully monitoring for spikes. A faulty VRM might be pushing high voltage through to the PCIe slot power pins. But a standard voltage measurement would probably just show a normal 12V+/5V+.
